Munin Cherokee plugin
by seeder • 7th December 2008 • post
Looked around to find out if there is one already and I couldn’t find any.
I’ve created a multifunctional plugin for Munin for monitoring Cherokee server.
It’s written in Ruby. So far I can confirm that it’s compatible with Munin 1.3.4 and Cherokee 0.11.3 on Gentoo.
It gets data from the server_info module available under /about , which has to be set to at least normal.
Plugin graphs will appear under cherokee category and I believe it allows you to monitor multiple servers from single munin-node as it uses the host field.
Plugin can monitor :
- Number of connections, Active, Open and Reusable
- Number of modules Loaded
- Data Transferred by the Server
- Data Transfer rate, but this is just a concept as it doesn’t yield usable data after a while.
How to use it
Place it in directory like
add executable bit
chmod +x /usr/local/lib/munin/plugins/cherokee__type_.rb
link from /etc/munin/plugins
cd /etc/munin/plugins ln -s /usr/local/lib/munin/plugins/cherokee__type_.rb cherokee_hostname_type_conn ln -s /usr/local/lib/munin/plugins/cherokee__type_.rb cherokee_hostname_type_mod ln -s /usr/local/lib/munin/plugins/cherokee__type_.rb cherokee_hostname_type_data ln -s /usr/local/lib/munin/plugins/cherokee__type_.rb cherokee_hostname_type_rate
